Eddie Royal arrived at Chargers Park on Thursday and clearly liked what he saw, agreeing to a three-year, $13.5-million contract, including $6 million guaranteed. The slot receiver, who spent his first four seasons with the Broncos, projects as a No. 4 wide receiver and punt returner.

On offense, Royal is a proven playmaker underneath with breakaway speed. He'll look to rebound from a rough 2011, slowed by groin and toe injuries before suffering a concussion on Dec. 4.

In 2010, Royal caught 59 passes for 627 yards and three touchdowns. He ranked third among wide receivers with an average of 6.9 yards after the catch. His best season came in 2008 when he totaled 91 receptions, 980 yards and five scores as a rookie.

Royal has averaged 11.9 yards per punt return since entering the league, third in the NFL over that span.

On Tuesday, the Chargers reached a four-year contract with wide receiver Robert Meachem. He signed Wednesday.

Whether the Bolts will be stronger at the position in 2012 despite losing Pro Bowler Vincent Jackson in free agency is up for debate.

But in three days, they became deeper.

When quarterback Philip Rivers evaluates the 2012 corps, he said one aspect is overlooked.

"Vincent Brown is going to be a big part of this thing, too," Rivers said this week. "He's not so much in the news right now because he's already here. That's what's so funny. You always get excited about the new guys you sign. But we've got guys who are here who are going to be good, too.

"I think Vincent Brown, with an offseason, unlike last year, is going to be big ... We're going to have a good group out there at wide receiver."
